Treatment of Perthes Disease in Early-Stage Evolution (Stage Ia, Ib, or IIa): Children Aged 7 or Older, or Younger with Femoral Head Extrusion
This protocol applies to Perthes disease diagnosed in the early stages of evolution — Stage Ia, Ib, or IIa — in children aged 7 years or older at onset, or in children under 7 where femoral head extrusion is already present.
Clinical Scenario
Children aged 7 or older at disease onset are at high risk of femoral head extrusion, and containment must be initiated as soon as the diagnosis is established. Children under 7 require close radiographic monitoring every 3–4 months; containment becomes necessary the moment extrusion is identified — without delay.
Treatment Approach (Partial Overview)
Management begins with restoring hip range of motion — a prerequisite for effective containment — followed by containment of the femoral head, achievable through conservative or surgical means. Weight-bearing avoidance is recommended alongside containment. The complete structured regimen, decision criteria, and procedural sequencing are in the full protocol.
Treatment Goals
Maintaining a spherical femoral head on hip radiograph; preventing or reversing lateral extrusion of the femoral head.

- Extrusion invariably occurs sooner or later in children over the age of 7 years at the onset of the disease and hence containment should be ensured as soon as the disease is diagnosed.
- In children under 7 years at the onset of the disease extrusion may or may not occur; these children need to be monitored closely with anteroposterior and frog-lateral radiographs, every 3 or 4 months and containment ensured as soon as extrusion is identified without any delay.
- The range of motion should be restored before effective containment can be achieved.
- Containment can be achieved by two different methods; the first involves keeping the hip in abduction and internal rotation or in abduction and flexion by casting, bracing or by surgery on the femur.
- The author advocates avoiding weight-bearing in addition to containment as some reports suggest that combining weight relief with containment may be beneficial.
